Abstract
In a compound miter saw or the like having a selectively rotatable turntable mounted on a supporting frame and a power driven saw blade pivotally mounted on the turntable between a lowered full cut position and a raised full retract position, the improvements comprising a work supporting fence that is maintained in alignment with a turntable slot while the turntable, including associated saw blade slot, is positioned for desired miter cuts; and the work supporting fence also being accurately and effectively clamped relative to the supporting frame, in both front and rear work supporting fence positions. Additional improvements include a swinging blade guard for the power driven saw blade having a pivot center eccentrically offset upwards from the shaft on which the saw blade rotates and back toward the pivotal mounting of the saw on the turntable, to facilitate access to the saw blade shaft and precludes interference with bevel cuts; and first and second transversely extending closed cylinders between the turntable and the saw, enabling pivotal movement of the saw between full cut and full retract positions, while also permitting bevel pivotal adjustment of the saw relative to the …
